I am trying sample application using spring boot + docker-compose + mysql. Below is my docker-compose,yml file

container_name: mysql-db
restart: always
command: --default-authentication-plugin=mysql_native_password
ports:
- "33061:3306"
networks:
- spring-boot-mysql-net
environment:
MYSQL_DATABASE: practice_db
MYSQL_ROOT_PASSWORD: root
volumes:
- ./database_storage:/docker-entrypoint-initdb.d
practice-service:
container_name: practice-service
build:
context: ./
dockerfile: Dockerfile
ports:
- "8080:8080"
depends_on:
- mysql
networks:
- spring-boot-mysql-net
restart: on-failure
command: sh -c './wait-for mysql:3306 -- npm start'
phpMyAdmin:

depends_on:

application. Properties

spring.datasource.url=jdbc:mysql://mysql:3306/practice_db
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver

But my spring boot application giving error while connecting to MySQLDB
2023-02-11 16:31:10 com.mysql.cj.jdbc.exceptions.CommunicationsException: Communications link failure
2023-02-11 16:31:10 The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.
2023-02-11 16:31:10 Caused by: java.net.ConnectException: Connection refused
Also I am trying to run phpMyAdmin but that is also not connecting to MySQL. I am not sure MySQL container is starting or not because I can see logs of it as -
